Can any good awk'er resolve this issue?
awk -F^ '{ if ((($1 != "M") && ($5 != "2")) || (($1 != "S") && ($5 != "7"))) print $0}' welcome > welcome1


The "&&" and "||" in the above command is not working with awk.

When I run the above command, the same content of welcome is copied to welcome1 without any difference.

Your reply is highly appreciated.

Thanks in advance.

Pls. check your if condition. For the data not to be copied the if condition should give FALSE.

Nothing is happening ...the command is just redirecting the contents of welcome to welcome1 without any difference.

pls find below welcome content

S^E^2008^12G43^7
C^E^2008^ZAT08^14
S^E^2008^ZAR48^22
M^E^2008^0TL69^2
S^E^2008^FCB67^30

The command is working fine. just added two lines to the file contents:

S^E^2008^12G43^7
C^E^2008^ZAT08^14
S^E^2008^ZAR48^22
M^E^2008^0TL69^2
S^E^2008^FCB67^30
M^hi^vi^5^7
M^E^2008^0TL69^7


Now you can see the result that the last two lines are not copied as per the if condition applied.

Regards,
Vinod.
